1.65 g (5.61 mmol) of 3-methoxycarbonyl-4-(2-pyrrolidin-1-ylethoxy)nitrobenzene (V.1.a) is dissolved in 100 mL of methanol and hydrogenated with hydrogen and 200 mg of Raney nickel as catalyst until the reaction is complete. Then the catalyst is filtered off and the solvent is eliminated. Yield: 1.43 g (97% of theory); Rf value: 0.15 (silica gel, methylene chloride/methanol/ammonia=9:1:0.1); C14H20N2O3; EII mass spectrum: m/z=265 [M+H]+.
